Actually, that makes sense. Java 2 has a different security structure

Generally, you should not need to unpack the jar files, nor is it
generally a good idea to do so, as they frequently contain fairly
complex directory structures that, if altered, will cause the VM to not
be able to find the classes it needs.

compiler options are as you would
normally use them ('-g' for debug, '-O' for optimization, etc.).
I also recommend reading the 'jdk1.2/include/jni.h' and
'jdk1.2/include//jni_md.h' files (where is your OS). The Java
Developers' Almanac has a nice section
the time, they don't even
get any kind of thanks or support from their users.
Frankly, I'm extremely impressed that they've come as far as they have

Have you tried 'java -green

Of course, you have to catch the possible IOException, so wrap that in a
